'Watches' in the Bible

so that your fasting will not be noticed by others but by your Father who is in the hidden place. And your Father who watches from the hidden place will reward you."

Otherwise, if he lays a foundation and can't finish the building, everyone who watches will begin to ridicule him

For the Lord watches the righteous, and he pays attention to their prayers. But the Lord opposes those who do wrong."

We know [with confidence] that anyone born of God does not habitually sin; but He (Jesus) who was born of God [carefully] keeps and protects him, and the evil one does not touch him.

(Behold, I come as a thief. Blessed is he that watches and keeps his garments, that he may not walk naked, and that they may not see his shame.)
